No, I haven’t found any info regarding how S1 does its stem separation; and I’ve done some looking. As you point out, this is a highly competitive domain with guarded trade secrets. In my mind, as I’ve mentioned before, the companies that will be successful will be those that have the foresight to engage with strong partners in the field. Developing this technical expertise in-house is all well and good until you find how long it can take. But collaborating with SMEs (Subject Matter Experts) doesn’t come cheap either, unless you can find a few 20-something grad students to join the team that are well connected to the IEEE Signal Processing Society or similar technical organization.


I’m not disputing that stem separation in Studio One works pretty well for me so far, but marketing companies are putting ‘AI’ in so many product descriptions now with no details, just because it sounds cool. How is this not just a good computer algorithm doing what it is programmed to do? What is it choosing to do that makes it simulate being intelligent?
This is a BIG question but for starters it’s about the number of parameters in your model. I’m hearing some good things about Banquet. This model has over 24 million parameters and is described as stem-agnostic as opposed to the 4 stem VDBO (Vocals, Drums, Bass, Other) that most separation models are limited to. I’m also hearing about better SNR performances compared to say, Spleeter.

Who knows, maybe Notion 7 “now with AI” will do wonders. For example, maybe it could look at my four trombone parts and tell me how I could voice them better. Now that would be intelligent.
This would be sweet with a capital S.
It “just” takes good model development.

For me there’s no better place in the band than to have one leg in the harmony world and the other in the percussive. Thank you Paul Tutmarc and Leo Fender.
